My partner, who keeps his hair very short (no 2) as he is thin on top, has noticed balding patches at the side. They started off small but are getting larger. The doctor thinks this is Alopecia areata. Can you recommend anything to alleviate this?

Alopecia areata can be due to overactivity of the immune system, thyroid problems, stress or fever. It can be an indication of a deficiency - vitamin C, iron and good multivitamin and mineral supplements may be enough to halt the process. If his skin and nails are dry, he may not be eating enough healthy oils from fish, nuts and seeds. There may be digestive problems, leading to malabsorption, in which case more systemic treatment is needed. Diluted essential oil of rosemary massaged into the scalp is recommended to stimulate growth. Use Green People's Rosemary Shampoo (£6.99, greenpeople.co.uk; or from independent health stores) and conditioner, which could be massaged into stimulate the scalp. If there's no difference in six to eight weeks, contact the National Institute of Medical Herbalists on 01392 426022 (nimh.org.uk).

Is there an effective natural way of lightening moles on the face? I had laser treatment to flatten raised moles and the pigment turned darker, as I was warned it might.

Unfortunately, there is little you can do. The only solution is a good camouflage cream to match your skin tone. Charles H Fox in Covent Garden, London (020-7240 3111, charlesfox.co.uk), makes it up for £16.95 and does colour matches for £20. Or contact the British Association of Skin Camouflage on 01625 267880 for more information.
